I hadn't finished assembling it and decided to add the binding strip on the part that was already quilted (bad idea!) (In my defence, I was going to visit a friend and wanted to bring some hand sewing for our visit!)
Later, I wanted to show it to a friend and so I rushed the rest of the assembly.
The entire thing started to go wonky and I hadn't noticed!
When I finished the quilt I couldn't believe how UN-square it was!! (how embarrassing ...with my experience!!)
I am going to remove the binding and square up the quilt and then reattach the binding and resew it by hand. I will never be able to use it knowing it isn't square!!!
Rushing is never a good thing.
NOTE: I undid the binding and marked the quilt edges to be equidistance from the horizontal centre seam line and just before I got the rotary cutter out I realized that if I trim the edges, the vertical seams of the panels will not be 90 Degrees with the edge. Oh brother!! I know that will bother me even more and will be more visible to my eye so I have decided to leave the quilt as is (I need to resew the binding on!!).
The good thing is I learned a trick for when I teach this class. I should start assembling it from the centre outward. Then turn the thing upside down and work the second side upside down from the centre outward.
